Transcript Kingdom Animalia

Kingdom Animalia
General Characteristics




Multicellular (made of more than 1 cell)
Eukaryotic (have a nucleus)
Heterotrophs (cannot make their own
food) that ingest their food
Lack cell walls



Cells are organized into tissues that make
up organs
Most reproduce sexually (DNA contributed
from 2 parents)
Most are motile (can move)
Animals are described according to their
arrangement of body part or symmetry.
Animal Kingdom Phyla
INVERTEBRATES - do not have a backbone
Phylum Porifera




Aquatic (live in the
water)
Lack true tissues &
organs
Sessile (can’t move)
adults
Filter feeders (strain
tiny floating
organisms from the
water)
Examples of Porifera
Venus Flower
Basket
Tube
Sponge
Bath Sponge
(loofah)
Phylum Cnidaria




Aquatic
Radial symmetry
(body plan in
which body parts
repeat around the
center of the body)
Tentacles bear
stinging
nematocysts
Some members
are sessile
Examples: Cnidarians
Portuguese man-of-war
Coral Reef
Moon Jellyfish
Sea Anemone
Phylum Platyhelminthes



Flatworms
Bilateral symmetry
(body plan in which
only a single,
imaginary line can
divide the body into
two equal halves)
Some free-living
and some parasitic
(live in and take in
nutrients from
another organism)
Examples: Flatworms
Planarian (free-living)
Liver Fluke (parasites)
Tapeworm (parasites)
• comes from undercooked
meats
Phylum Nematoda


Roundworms
Digestive system
has two openings –
a mouth and an
anus (this is the
first group of
Animals that has
this trait)
Examples: Roundworms
Trichinella
Hookworm
Filaria worm
Phylum Annelida



Segmented worms
Digestive system
has 2 openings
Closed circulatory
system (blood is
contained within a
network of blood
vessels)
Examples: Segmented Worms
Fanworm (live in salt
water)
Earthworm (terrestrial- live
on land)
Leech (most live in
fresh water)
Phylum Mollusca



Soft-bodied; often with a hard shell
Digestive system with 2 openings
Muscular foot – can be used for crawling,
burrowing or as tentacles to capture prey
Examples: Mollusks
Scallop
Oyster
Clam
Octopus
Snail
Slug
Squid
Phylum Arthropoda




Exoskeletons (external
skeleton)
Jointed appendages
(structures such as legs
and antennae that extend
from the body wall)
Open circulatory system
(blood is not always
contained within a network
of blood vessels)
Largest animal phylum
Examples: Arthropods
Tick
Trilobite
Crab
Centipede
Scorpion
Spider
Crayfish
Millipede
Barnacles
Ant
Grasshopper
Phylum Echinodermata




Live in salt water
Spiny Skin
Radial symmetry in adults
Endoskeleton (internal skeleton)
Examples: Echinoderms
Sea Lily
Sea Star
(starfish)
Brittle Star
Sea Cucumber
Sea Urchin
Sand Dollar
Phylum Chordata


Dorsal (runs along
the back), hollow
nerve cord
Tail during at least
part of
development
Subphylum Urochordata

fresh & salt water; no jaws; circular
mouth lined with toothlike structures;
example: lampreys

endoskeleton of
cartilage; most

endoskeleton of bone; aquatic
